ELEVATINGi'v 0R SEPARATING JACK FOR ELECTRICAL CABLES OR WIRES.

' To all whom igfonay conccrm,

Be it known that I, THOMAS COPE, a citizen of the United States,residing in the city andcounty of Philadelphia, :State of Pennsylvania,have invented a new and jaws forming normally a wedge shaped body, andmeans for separating the jaws whereby when said body is inserted betweenthe proper'wires-or cables and said means are operated, the relativewires or cables' are raised or separated thus rendering convenientaccess to the broken or impaired wires or cables when repairs or othertreatment of the same may be accomplished.

The invention is satisfactorily illustrated` in the accompanyingdrawing, but the important instrumentallties thereof may be varied, andso 1t 1s to beunderstood that 'the invention is not limited to thespecilic arrangement and organization shown anddescribed. v

Figs. 2 and il representllingitudinal sections thereof with the members respectively 1n normaland operated conditions. Fig. 4: represents a partial plan view andpartial horizontal section of the under member of the jack on anenlarged scale. Fig. 5 represents a perspective view of a' portion of a.detached member thereof. Fig. 6 represents a transverse section on line.fc-m Fig. 3. Fig. 7 represents a perspective -viewv of another memberof the invention. Fig. 8 represents a longitudinal lsection of anotherform of the invention with its members in` normal condition. Fig; it)represents asimilar section with the members in operated condi-A tion.Fig. 10 represents a horizontal section on line'y-y Fig. 9. Fig. 11represents a. transverse section on line z-z Fig. '9.

Similar letters of'reference indicate corresponding parts 1n thefigures.

Referring to the drawings. lA designates y the` body of the device, thesame comprising the stationary jaw C, the movable jaw B and the togglelevers D `intermediate of said jaws, one limb of each of said leversbeing pivotally lconnectedwith the ears E' on the jaw B, and the` otherlimb of each of which is slidingly connected with the ways F on the jawC; Depending fronrthe jaw B arev the shoes G and rising from the jaw Care the shoes H, said shoes being adapted to contact, the contactingfaces being inclined or wedge shaped, as will be referred to more fullyhereafter. Y

J designates a bar or rod adapted to impart draft to the jaw A, the samebeing vpivot'a'llyy connected at its forward end with *the ear K', thelattenbeing secured to the undersidefof the jaw B. ,The rear end of saidbar is pivotally connected with the elevis L, the latter having swiveledto it, the end of the screw M, on which is tted the nut N, the innerface of which is concave and has a bearing in a conical recess P iormedin the rear wall Q, of the jaw C by which'provision said screwis enabledto change its position angularly with the motions of the bar J, asplainly illustrated in Figs. 2 and 3. The screw M is provided withA ahead lt for attachment of 'a suitable handle whereby the former may berotated lVhen the parts are in' position shown in Figs. l` and 2, thedevice is inserted between `opposite banks or tiers of cables or wireswhere access to a broken cable or wire, is

desired, the device resting on what may be termed the under -rows orsets of cables or wires as its support.

operated whereby the bar J draws the jaw B in the present case to theright. The shoes G then ride on the shoes H and impart a certainelevation to said jaw B. As the front limbs D of the toggle D follow themotion of said jaw, the rear limbs D2 slide rearwardly in the ways F andso allow said front limbs D to in a radial direction to the requiredextent without bind- Then the screw is `may be termed the upper rows orsets of cables or wires, a space is provided thereby which permitsaccess to the broken cablel or wire atthe existing place adjacent to thedevice where the same occurs.

When the screw is rotated in reverse di-l rection the bar .I advancesthe jaw B to the front when the movable members assume their normalpositions and said jaw lowers and isv seated on the jaw C. When thedevice is closed again, as shown in Figs. 1 and 2, the bar J may bedisconnected from the jaw B and removed with the clevis L, the screw M,and the nut N fromtthe rear wall Q of the jaw C, and in lieu of saidscrew and bar, I may employ the rope or cable T which is connected withthe ear K and adapted to bel wound around the roller U which is mountedon the wall Q and which by its rotation serves to cause the draftimparted to the rope'or cable T to move the' jaw B to the right whensaid jaw begins its elevation as in the previous case.

The limbs D2 of the toggles D and openings in the ways F which receivesaid limbs are rhomboidal in cross section, see Fig. 5, so that whilesaid limbs' may slide freely in said ways they are prevented from risingtherein and so cause the toggle levers and l the jaws to remainconnected.

In Figs. 8, 9, 10 and 11, I show a con--` struction similar in generalrespects to that of the previous figures excepting that each jaw has asingle shoe G H respectively and excepting the toggle levers have each asingle lower limb, the same being of the form of a slide D3 which restson the base of the lower jaw B and is movable thereon and operativesimilar to the limbs D2 of the construction illustrated in tl1e.prcviousfigures.

Having thus described my invention what I claim as new and desire tosecure by Letters uPatent, is

1. In an elevating device of the character stat-ed, stationary andmovable jaws, and

longitudinally movable swiveled screw means connected with said jawsadapted to impart longitudinal draft to the movable jaws.

2. In an elevating device of the character.

-ing means lnterposed between the same adapted to separate one jaw fromanother lirstby draftl on said jaw, and next by with said jaws.

4. In an elevating device of the character stated, stationary andmovable jaws, means connected with Vsaid jaws for imparting 1ongitudinaldraft to the movable jaw, means for primarily separating the movable jawfrom the stationary jaw,and swiveled screw radial action of a leverwhich is connected means for further separating said movable i.

jaw to complete operative position.

5; In an elevating device of the character stated, stationary andmovable jaws, means connected with said ja'ws for imparting longitudinaldraft to the movable jaw, shoes with inclined faces on the jaws adaptedfor primarily separating themovable jaw, and a toggle 'lever having its`limbs connected with the opposite jaws and adapted for furtherseparating the movable jaw to 'completeoperative position. v

6. In an elevating device of the character stated, stationary andmovable jaws, means for imparting longitudinal draft to the movable jaw,and means for opening the latter, said first named means consisting of a'draft bar, a rotatable screw, said bar being pivotally connected withsaid screw and with the movable jaw, and a nut on said screw, said nuthaving a turnable bearing on a member of the stationary jaw, said sorewpassing freely through said member.
